18. Should we fight bacteria? “ The Silver Nano Health System is a comprehensive system developed by Samsung to improve your quality of life by eliminating bacteria from the places that count most.....Just as a dirty washer never truly cleans clothes… Samsung has found a solution in the safety of silver , ionizing silver into ions for an effective coating that lets your home appliances remain remarkably free of bacteria and odors. ”

Editor's Notes
Bacteria that are harmful Silver that can protect Consumers / families that are concerned But nanosilver is not killing all bacteria Focus is taken away from why we have pathogene bacteria where
